I think they know they are not a contender this season. They may aim at top four which is still very hard to finish for Chelsea.
Don't be quick to write the blues off, the team has always been one with a fighting spirit. ....snip
Yes, maybe this season has been one of the toughest seasons for Chelsea regarding the players in the squad. Moreover, some of Chelsea's target players could not be obtained. However, Chelsea is a big club, the transfer window is still running, and there is still a chance to get other reliable players. They are also negotiating some players who are capable enough to fill and strengthen the squad. So, even though it's not easy, I still believe that Chelsea can still be strong in the future. Maybe there will be a great surprise in the near future?
Chelsea has signed enough for the season. I think what Tuchel needs at the moment is to sit down and draft a working formation that suits his current squad. you don't use an old vessel for a new wine it might likely burst. Lets tell ourselves the truth no new signings can perfectly replace Antonio Rudiger and Andreas Christensen not even koulibaly nor the new centre back Skriniar from Milan but with steady formation testing Tuchel could come up with a working setup that suits the club.
